function hook_ape_cache_expiration_alter in Advanced Page Expiration 7

Alter the max_age before being set.

This hook is called right before the cache header is set. It can therefore be used to set the cache header regardless of any other state in the system, including whether caching is enabled or a user is logged in.

For that reason, it is important that the function ape_check_cacheable() is used if the standard caching logic should still be respected.

Parameters

int $max_age: Set this to the new desired value.

int $original_max_age: The original set value so it can be used for comparison.
